Minnesota firms were joined by companies nationwide to attend a Medical Trade Mission to India March 2-8 to take advantage of a rapidly growing middle-class whose healthcare consumption is increasingly hard to ignore. The Indian healthcare industry is estimated to be $50 billion and is expected to reach over $75 billion by the end of the year, according to a Department of Commerce memo promoting the mission. Seventeen companies attended the Medical Fair India trade show and representatives from 14 of those companies traveled to Hyderabad and New Delhi that were also on the itinerary, said September Secrist, an international trade specialist, with the U.S. Commercial Service, part of Commerce.
